(Cl. 10S-3) 3 Claims.

The present invention relates to umbrellas, canopies and the like ornamental rooflike structures and more particularly to a rigid or permanently ventilated covering for use in opened places such as lawns, patios, gardens, beaches, decks and the like and which can be subjected to and endure all kinds of weather.

The primary object of the present invention is to provide a covering for umbrellas which will repel the light and sun rays, form a protection against rain and have Ventilating characteristics for not only reducing the temperatures beneath the covering but permit the umbrella to maintain its equilibrium upon its support when subjected to ordinary gusts of wind.

Another equally important object -of the invention is to form an umbrella from pressed or molded metals, wood, plastics and the like rigid materials which can be standardized and readily and economically assembled into the finished products rendering the same comparatively inexpensive in the cost of manufacture and thereby rendering the same commercially desirable.

Other objects of the invention will be in part obvious and in part pointed out as the description continues.

In the accompanying drawings:

Fig. 1 is a fragmentary top plan view of the umbrella embodying the present invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a vertical transverse sectional view taken on the line 3--3 of Fig. 1 in the direction of the arrow points.

Fig. 4 is a detail sectional view taken on the line 4-4 of Fig. 1 in the direction of arrow points.

Fig. 5 is another detail section taken on the line 5-5 of Fig. 1 in the direction of arrow points.

Fig. 6 is a detail plan View of a section of the umbrella showing a slightly modified form of the invention.

Fig. 'l is a sectional view taken on the line 1-1 of Fig. 6 in the direction of the arrow points, and

Fig. 8 is a detail sectional view showing a modified form of connection between the vanes of the umbrella and its support forming ribs.

The umbrella as herein shown is o f the conventional circular type or design. but it, of course, can be of a square, rectangular, hexagon, Octagon or similar configuration, or may be arranged in multiple sections and the sheets, tubes and other parts thereof are preferably made from more or less rigid material such as wood, plastics, and metals or metal alloys or a combination of such materials in laminated or molded form.

However, when employing wood, the same should be laminated and impregnated with a waterproofing composition, but we preferably employed a metal such as aluminum, having its outer surface, or that surface which is exposed to the suns rays to be highly polished so as to reflect the heat therefrom. Also the vanes of the umbrella may be painted in any color or combination oi colors and fringe of the same material or of cotton or leather may be attached to the outer marginal edges thereafter add to the ornamental features of the umbrella.

The supporting post I may be part of a lawn table, driven into the ground or attached to any other appropriate supporting base and has a socket 2 for receiving the lower end of a center handle or rod 3 of the umbrella which latter may be adjustably connected to the post I whereby it may be tilted and retained at various angles to its supporting base or table.

Formed with the rod 3 is an annular flange 4 upon which rests a hub member comprising a lower circular plate 5 and retained upon the rod and plate 5 by means of an adjustable and removable knob 6 is a disc 1. In the annular groove formed between the plate 5 and disc l restV the inner ends of its vanes 8 and permanently connected by suitable fastening elements or the rivets as shown.

These vanes 8 are fan-shaped sheets of material palmately arranged in superimposed and spaced relation having their smaller inner ends radiating from the center rod or handle 3 and their widened outer extremities secured to a tube 9. The upper row or section of vanes are each slightly bowed to give to the umbrella the desired outer contours and their outer extremities are bent around the tube 9. The lower or inner section of vanes are bent downwardly as at I 0 and then bowed to correspond with the upper vanes with their outer extremities bent around the outer ends of the upper vanes whereas the vanes may be secured by spot welding to the tube 9.

Instead of spot welding the vanes to the tube 9, we may secure the same to the latter by bending or crimping the outer extremities of the lower set of vanes about the outer ends of the upper set of vanes and tube 9 in the manner as best shown in Fig. 8 of the drawings.

To retain the upper and lower set of vanes in spaced relation we preferably arrange therebetween two circular tubes Il and I2 which are secured to the vanes by spot welding or in other ways customary in the trade.

The vanes of the upper set are arranged in staggered relation with regard to the vanes of the lower set whereby the upper vanes slightly overlap the lower vanes to exclude the sun rays and yet provide for the free circulation of air between the vanes as is best shown by the arrows in Figure 4.

The Vanesmaybe: crimpedzorcorrugated as shown in Figs. rf5 and 7 whereby the small undulae tions thereof extend longitudinally to the outer ends of the vanes so that water may freely flow? therefrom, Instead of employing the tubes 9,

I I and I2 for connecting and retaining the vanes in spaced relation, rivets I3 may be -femployed-i The outer extremities of thesescorrugated.vanes.

I4 may be rounded as at I5 or of any othertsuitable ornamental design.

From the foregoing it will befunderstoodthat the inner ends of the vanes are nestedand:

secured between the plates 5 and 'I of the hub member. as shown in Fig.. 5,-whereby the entirecovering mayberemoved .from the handle. 3 byv simpl-y removing` the. knob 5. and stored when not', in. use,. thereby reducing the amount. ofY storage space necessary,V These rigidly retained vaneswlien made.l from aluminum Aor similar metals should have .their t outer surfaces highly polished.; to. reil'ectback the `heat ,from the suns rays andiobviously wilInot fade', rust or depreciate when exposed-Lto all kinds .of weather.thereby greatly. increasing the. life of the umbrella. over.
